Description

La présente invention concerne un appareil tel qu'une machine à laver le linge ou la vaisselle, un appareil à distribution de produit en solution, etc..., muni de boîtes à produits.The present invention relates to an apparatus such as a washing machine for washing clothes or dishes, an apparatus for dispensing product in solution, etc., provided with boxes for products.

Dans une machine à laver, par exemple, des produits lessiviels en poudre ou en liquide sont habituellement utilisés et les boîtes ou bacs connus qui les contiennent, sont conçus de manières différentes. Quand il s'agit d'un produit en poudre, la boîte ou le bac d'entreposage connu comprend fréquemment soit une paroi latérale ouverte de haut en bas soit un ou plusieurs trous formés au niveau de son fond, destinés à l'évacuation du produit. Dans une telle boîte ou bac, le produit en poudre déposé dans un endroit éloigné de cette paroi ouverte ou ces trous, en absence de l'eau, reste en tas et ne s'en va pas ou ne se déverse pas dans la cuve de la machine. Lors d'une introduction de l'eau dans cette boîte ou bac, le produit pulvérulent est entraîné par l'eau à travers cette paroi ouverte ou ces trous, dans la cuve de la machine.In a washing machine, for example, detergents in powder or liquid form are usually used and the known boxes or tubs which contain them are designed in different ways. In the case of a powdered product, the known storage container or box frequently comprises either a side wall open from top to bottom or one or more holes formed at its bottom, intended for the evacuation of the product. In such a box or tray, the powdered product deposited in a place remote from this open wall or these holes, in the absence of water, remains in a heap and does not go away or spill into the tank. the machine. When water is introduced into this box or tank, the pulverulent product is entrained by the water through this open wall or these holes, in the tank of the machine.

Par contre pour un produit liquide, la boîte ou le bac d'entreposage comprend des parois fermées, et l'évacuation du produit se fait habituellement par un siphon qui s'amorce après une adjonction d'eau dans cette boîte ou bac.On the other hand, for a liquid product, the storage box or tank has closed walls, and the product is usually discharged by a siphon which starts after adding water to this box or tank.

Dans les appareils connus, ces boîtes ou bacs d'entreposage conçus pour un produit pulvérulent ne sont pas aptes à recevoir un produit liquide ou inversement quand ces boîtes sont prévues pour un produit liquide, elles ne fonctionnent pas correctement pour un produit pulvérulent. Un changement d'état physique des produits lessiviels utilisés exige un changement de type de boîte ou l'utilisation d'un dispositif d'adaptation.In known devices, these boxes or storage tanks designed for a pulverulent product are not capable of receiving a liquid product or conversely when these boxes are intended for a liquid product, they do not function correctly for a pulverulent product. A change in the physical state of the detergents used requires a change in the type of box or the use of an adaptation device.

Ces solutions onéreuses grèvent le prix de revient de l'appareil fabriqué.These expensive solutions add to the cost price of the device manufactured.

Comme le document EP-A-0083532 (qui appartient à l'état de la technique selon l'article 54 (3) CBE). la présente invention ayant pour but d'éviter ces inconvénients, permet de réaliser un appareil économique dans lequel une boîte universelle à produits peut fonctionner indifféremment avec un produit pulvérulent liquide ou pâteux.Like document EP-A-0083532 (which belongs to the state of the art according to Article 54 (3) EPC). the object of the present invention is to avoid these drawbacks, makes it possible to produce an economical device in which a universal product container can operate equally well with a liquid or pasty pulverulent product.

Selon le document EP-A-0 083 532 un appareil muni de boîtes à produits dont la distribution au cours du fonctionnement de cet appareil, se fait par évacuation d'un mélange formé de ces produits et d'un liquide tel que de l'eau injecté dans ces boîtes, comprend comme boîtes à produits, au moins une boîte universelle fonctionnant à courant d'eau d'entraînement et à déversement par trop plein.According to document EP-A-0 083 532 a device provided with boxes of products whose distribution during the operation of this device, is done by evacuation of a mixture formed of these products and a liquid such as water injected into these boxes, includes as product boxes, at least one universal box operating with a flow of drive water and overflow.

Cette boîte universelle comprend un trou d'évacuation d'eau dont le diamètre est déterminé de manière à laisser passer l'eau tout en empêchant le passage des produits liquides. Cependant il est délicat d'y empêcher une fuite de produits liquides dont la viscosité est voisine de celle de l'eau.This universal box includes a water drainage hole whose diameter is determined so as to let the water pass while preventing the passage of liquid products. However, it is difficult to prevent a leak of liquid products whose viscosity is close to that of water.

La présente invention apporte à l'objet du document EP-A-0 083 532 des perfectionnements qui permettent d'améliorer son fonctionnement et d'éviter les inconvénients ci-dessus.The present invention provides the subject of document EP-A-0 083 532 with improvements which make it possible to improve its operation and to avoid the above drawbacks.

Selon la présente invention, un appareil tel qu'un lave-linge ou lave-vaiselle muni d'une boîte universelle à produits pulvérulents, liquides ou pâteux fonctionnant à courant d'eau d'entraînement et à déversement par trop plein, comprend en combinaison, dans cette boîte à produits, au moins un seuil de rétention des produits dans la boite, un déflecteur et un siphon ou dispositif de siphonnage, disposés sur le trajet du courant d'eau d'entraînement crée par un jet d'eau lesquels donnent à cette boîte à produits une aptitude à recevoir tous produits lessiviels pulvérulents, pâteux ou liquides quel que soit leur degré de viscosité, et réalisent l'évacuation de ces produits à la fois par déversement par trop plein à travers ce seuil et par transvasement par siphon à travers ce dispositif de siphonnage.According to the present invention, an apparatus such as a washing machine or dishwasher provided with a universal box for pulverulent, liquid or pasty products operating with a flow of entrained water and with overflow, comprises in combination , in this product box, at least one threshold for retaining the products in the box, a deflector and a siphon or siphoning device, arranged on the path of the drive water current created by a water jet which give to this product box an ability to receive all powdery, pasty or liquid detergents whatever their degree of viscosity, and carry out the evacuation of these products both by overflow overflow through this threshold and by siphon transfer through this siphoning device.

Pour mieux faire comprendre l'invention on décrit ci-après un exemple de réalisation illustré par des dessins ei-annexés dont

  • la figure 1 représente une vue partielle et schématique d'une machine à laver le linge à chargement par le dessus, réalisée selon le document EP-A-0 083 532 montrant la porte de la machine, dans une position de fermeture,

In order to better understand the invention, an exemplary embodiment is illustrated below, illustrated by attached drawings, of which
  • FIG. 1 represents a partial and schematic view of a top-loading washing machine, produced according to document EP-A-0 083 532 showing the door of the machine, in a closed position,
  • 2 shows a partial and schematic view of the machine of Figure 1, in section along a plane II-II.
  • FIG. 3 represents a partial and schematic view of a washing machine made according to the invention, showing the door of the machine, in a closed position, and
  • 4 shows a partial and schematic view of the machine of Figure 3, in section along a plane IV-IV.

Une machine à laver le linge 1, selon le document EP-A-0 083 532 illustrée dans les figures 1 et 2, comprend une carrosserie 2, une cuve 3 et un tambour à linge 4. La machine 1 à chargement par le dessus, est formée par une porte 5 pivotant autour d'un axe horizontal 6.A washing machine 1, according to document EP-A-0 083 532 illustrated in FIGS. 1 and 2, comprises a body 2, a tank 3 and a washing drum 4. The machine 1 for top loading, is formed by a door 5 pivoting about a horizontal axis 6.

La porte 5 est munie dans sa surface intérieure 7 au moins d'une boîte universelle à produits 9 fonctionnant à courant d'eau d'entraînement et à déversement par trop plein. Cette porte 5 comprend un ensemble amovible 8 de deux boites universelles jumelées 9 et 10, pour produits lessiviels pulvérulents, liquides ou pâteux en saillie dans l'ouverture 11 de la cuve 3 lors d'une mise de cet ensemble 8 dans sa position de fonctionnement, par une fermeture de la porte 5.The door 5 is provided in its inner surface 7 with at least one universal product container 9 operating with a flow of drive water and overflow. This door 5 includes a removable assembly 8 of two twin universal boxes 9 and 10, for powdery, liquid or pasty detergents projecting into the opening 11 of the tank 3 when this assembly 8 is put in its operating position. , by closing door 5.

Suivant cette position de fonctionnement de l'ensemble 8, les boîtes universelles 9 et 10 comprennent respectivement des parois latérales cylindriques 12, 13, des parois d'extrémité 14, 15, 16, 17 et des entrées 18, 19 prolongées latéralement par des becs en forme d'entonnoirs 20, 21. Les entrées 18, 19 sont formées dans les parois latérales cylindriques 12, 13 sur une partie seulement de leur largeur ou hauteur, et plus près des parois d'extrémité 14, 16 qui représentent les parois supérieures des boîtes 9 et 10 quand l'ensemble 8 se trouve dans sa position de fonctionnement. Il en résulte que dans cette position de fonctionnement des boîtes 9 et 10 (figure 1), les parois d'extrémités 15,17 qui représentent les parois inférieures, se trouvent à un niveau inférieur à celui des seuils 22, 23 des entrées 18, 19. Cette dénivélation ou la hauteur des seuils 22, 23 définit la dose maximale de produit notamment liquide pouvant être retenue par les boites 9 et 10. Si sa quantité est trop importante, le produit liquide s'évacue par débordement de ces seuils 22, 23 selon un déversement par trop plein. Quand l'ensemble 8 est mis dans sa position de recharge par soulèvement de porte 5 dans sa position verticale non représentée, les entrées 18 et 19 des boîtes 9 et 10 sont orientées vers le haut, et les becs en forme d'entonnoirs 20, 21 facilitent le remplissage de ces boîtes en produits lessiviels pulvérulents, liquides ou pâteux. Lors d'une remise de cet ensemble 8 dans sa position de fonctionnement (figure 1) les doses de produits lessiviels se trouvant dans les boites 9 et 10 sont retenues par les seuils 22, 23 des entrées 18, 19. Les boîtes universelles 9 et 10 comprennent en outre respectivement dans leurs parois d'extrémités 15, 17 qui représentent leurs parois inférieures dans leur position de fonctionnement (figure 1 des trous 30 et 31 d'évacuation d'eau. Etant donné que la plupart des produits liquides utilisés ont un degré de viscosité supérieur à celui de l'eau utilisée dans les machines à laver, les diamètres de ces trous d'évacuation sont déterminés de manière qu'ils laissent passer de l'eau mais empêchent le passage de ces produits liquides.According to this operating position of the assembly 8, the universal boxes 9 and 10 respectively comprise cylindrical side walls 12, 13, end walls 14, 15, 16, 17 and inlets 18, 19 extended laterally by spouts funnel-shaped 20, 21. The inlets 18, 19 are formed in the cylindrical side walls 12, 13 over only part of their width or height, and closer to the end walls 14, 16 which represent the upper walls of the boxes 9 and 10 when the assembly 8 is in its operating position. It follows that in this operating position of the boxes 9 and 10 (FIG. 1), the end walls 15, 17 which represent the lower walls, are at a level lower than that of the thresholds 22, 23 of the inputs 18, 19. This difference in level or the height of the thresholds 22, 23 defines the maximum dose of product, in particular liquid, which can be retained by the boxes 9 and 10. If its quantity is too large, the liquid product is evacuated by overflowing of these thresholds 22, 23 according to an overflow spill. When the assembly 8 is put in its recharging position by lifting the door 5 in its vertical position not shown, the inlets 18 and 19 of the boxes 9 and 10 are oriented upwards, and the spouts in the form of funnels 20, 21 facilitate the filling of these boxes with powdery, liquid or pasty detergents. When this assembly 8 is returned to its operating position (FIG. 1), the doses of detergents found in the boxes 9 and 10 are retained by the thresholds 22, 23 of the inputs 18, 19. The universal boxes 9 and 10 further comprise respectively in their end walls 15, 17 which represent their lower walls in their operating position (FIG. 1 of the water drainage holes 30 and 31. Since most of the liquid products used have a degree of viscosity higher than that of the water used in washing machines, the diameters of these drainage holes are determined so that they allow water to pass but prevent the passage of these liquid products.

La machine à laver 1 comprend en outre d'une part un système d'injection d'eau 24 du type connu dont les buses 25, 26, 27 sont schématiquement représentées dans la figure 2, et d'autre part certains bacs de type connu 28, 29 pour des produits tels que assouplissant, eau de javel etc... Le système d'injection d'eau 24 commandé par un programmateur de type connu non représenté, est monté dans la machine à laver 1, en vis à vis des boîtes universelles 9 et 10 et des bacs 28, 29 à produits (figures 1 et 2). Ce système 24 permet d'envoyer par la buse 25 un jet d'eau 32 à travers l'entrée 19 dans la boite universelle 10, presque tangentiellement à la paroi cylindrique 13 de celle-ci, par la buse 26, un jet d'eau 33 à travers l'entrée 18 dans la boîte universelle 9, presque tangentiellement à la paroi cylindrique 12 de celle-ci, par les deux buses 25, 26 de l'eau, résultant de la collision des jets d'eau 32 et 33, et recueillie par une gouttière 34, dans le bac 29, et par la buse 27, un jet d'eau 35, à travers un trou 36 de la paroi 37, dans le bac 28.The washing machine 1 further comprises on the one hand a water injection system 24 of the known type, the nozzles 25, 26, 27 of which are schematically represented in FIG. 2, and on the other hand certain tanks of known type 28, 29 for products such as fabric softener, bleach etc ... The water injection system 24 controlled by a known type of programmer not shown, is mounted in the washing machine 1, opposite the universal boxes 9 and 10 and trays 28, 29 for products (Figures 1 and 2). This system 24 makes it possible to send a jet of water 32 through the nozzle 25 through the inlet 19 into the universal box 10, almost tangentially to the cylindrical wall 13 thereof, via the nozzle 26, a jet of water 33 through the inlet 18 in the universal box 9, almost tangentially to the cylindrical wall 12 thereof, by the two water nozzles 25, 26, resulting from the collision of the water jets 32 and 33 , and collected by a gutter 34, in the tank 29, and by the nozzle 27, a jet of water 35, through a hole 36 in the wall 37, in the tank 28.

Les boîtes universelles 9 et 10 et les bacs 28, 29 étant remplis de leurs doses respectives de produits et mis en position de fonctionnement par la fermeture de la porte 5, à un moment déterminé du cycle de lavage où le produit dans la boîte universelle 9 par exemple doit être distribué dans la cuve 3 de la machine 1, la' buse 26 envoie un jet d'eau 33 dans la boîte 9. Ce jet d'eau, qui est presque tangentiel à la paroi latérale cylindrique 12, engendre un mouvement circulaire d'eau et crée en conséquence un courant qui entraîne au passage le produit pulvérulent, liquide ou pâteux se trouvant dans la boîte 9. Le mélange d'eau et de produits, guidé par le bec 20, se déverse dans la cuve 3 dès que son niveau dépasse le seuil 22 de l'entrée 18. Dans la boîte universelle 9, ce mélange étant fortement concentré en produits au début de l'injection d'eau, se dilue progressivement par l'arrivée de l'eau et par l'évacuation du mélange par trop plein, et devient, à la fin de l'opération, uniquement de l'eau. Le programmateur arrête le jet d'eau 33, et l'eau résiduelle restant dans la boîte universelle 9 s'évacue par le trou 30 et tombe dans la cuve 3.The universal boxes 9 and 10 and the tanks 28, 29 being filled with their respective doses of products and placed in the operating position by closing the door 5, at a determined time in the washing cycle where the product in the universal box 9 for example must be distributed in the tank 3 of the machine 1, the 'nozzle 26 sends a jet of water 33 into the box 9. This jet of water, which is almost tangential to the cylindrical side wall 12, generates a movement circular flow of water and consequently creates a current which drives the pulverulent, liquid or pasty product in the box 9 in passing. The mixture of water and products, guided by the spout 20, pours into the tank 3 as soon as that its level exceeds the threshold 22 of the entry 18. In the universal box 9, this mixture being highly concentrated in products at the start of the water injection, is gradually diluted by the arrival of the water and by the evacuation of the mixture by overflow, and becomes, at the end of the operation, only ent water. The programmer stops the water jet 33, and the residual water remaining in the universal box 9 is evacuated through the hole 30 and falls into the tank 3.

Le fonctionnement de la boîte universelle 10 avec le jet d'eau 32 envoyé par la buse 25 est analogue à celui de la boîte universelle 9, décrit ci-dessus.The operation of the universal box 10 with the water jet 32 sent by the nozzle 25 is similar to that of the universal box 9, described above.

Dans certains cas où la viscosité d'un produit liquide utilisé est grande ou un produit pulvérulent mouillé a tendance à se coller à la boîte 9 ou 10, il arrive que le courant d'eau crée par le jet d'eau 33 ou 32 est insuffisamment tourbillonnaire pour pouvoir soulever et entraîner efficacement le produit.In certain cases where the viscosity of a liquid product used is high or a wet powdery product tends to stick to the can 9 or 10, it sometimes happens that the current of water created by the jet of water 33 or 32 is insufficiently swirling to be able to lift and drive the product effectively.

Dans d'autres cas où la viscosité d'un produit liquide utilisé est voisine de celle de l'eau, il arrive que le trou d'évacuation d'eau 30 ou 31 ne peut retenir efficacement ce produit dans la boîte 9 ou 10 jusqu'au moment de sa distribution.In other cases where the viscosity of a liquid product used is close to that of water, it happens that the water drainage hole 30 or 31 cannot effectively retain this product in the box 9 or 10 until 'at the time of its distribution.

La présente invention permet d'éviter ces inconvénients.The present invention makes it possible to avoid these drawbacks.

Selon l'invention dans les boites universelles 9 et 10, sur le trajet des courants d'eau créés respectivement par les jets d'eau admise 32,33 au moins un déflecteur 40, 41 qui détourne une partie de ces courants d'eau pour la diriger de nouveau contre ces courants en vue d'y former des remous augmentant l'action tourbillonnaire de soulèvement et d'entrainement des produits. Les déflecteurs 40 et 41 sont constitués par des cloisons fixées par au moins un de leurs bords à une des parois des boîtes 9 et 10, et les autres bords restant libres faisant saillie dans ces courants d'eau d'entrainement.According to the invention in the universal boxes 9 and 10, on the path of the water currents created respectively by the water jets admitted 32,33 at least one deflector 40, 41 which diverts part of these water currents for direct it again against these currents in order to form eddies increasing the swirling action of lifting and entrainment of the products. The deflectors 40 and 41 consist of partitions fixed by at least one of their edges to one of the walls of the boxes 9 and 10, and the other edges remaining free projecting in these driving water streams.

Dans t'exempte illustré aux figures 3 et 4, les déflecteurs 40 et 41 sont fixées par trois de leurs bords contre les parois latérales cylindriques 12 et 13 et les parois d'extrémités 14, 15, 16, 17. Les déflecteurs 40 et 41 peuvent se situer à un niveau quelconque du trajet des courants d'eau créés par les jets d'eau 32, 33 sans gêner l'entrée de ces jets d'eau dans les boîtes 9 et 10.In the example illustrated in FIGS. 3 and 4, the deflectors 40 and 41 are fixed by three of their edges against the cylindrical side walls 12 and 13 and the end walls 14, 15, 16, 17. The deflectors 40 and 41 can be located at any level of the path of the water currents created by the water jets 32, 33 without hindering the entry of these water jets into the boxes 9 and 10.

Dans l'exemple illustré, les déflecteurs 40 et 41 sont fixés dans le voisinage du bord des ouvertures d'entrée 18, 19 des boîtes 9 et 10 du côté amont des courants d'eau d'entraînement de celles-ci.In the example illustrated, the deflectors 40 and 41 are fixed in the vicinity of the edge of the inlet openings 18, 19 of the boxes 9 and 10 on the upstream side of the driving water streams thereof.

Selon l'invention dans les boîtes 9 et 10, les trous d'évacuation d'eau formés par des orifices percés dans les parois d'extrémités 15 et 17 sont supprimés. Des dispositifs de siphonage 42, 43 sont formés respectivement dans chacune de ces boîtes 9 et 10 en amont d'un obstacle disposé sur le trajet des courants d'eau créés respectivement par les jets d'eau admise 32, 33. Dans l'exemple illustré, cet obstacle est constitué par un des déflecteurs 40, 41. Cet obstacle ou déflecteur crée des remous et une surpression dans le courant d'eau admise qui font monter le niveau d'eau à cet endroit des boîtes 9 et 10 et provoquent l'amorçage de ces dispositifs de siphonnage. Ces dispositifs de siphonnage comprennent un tuyau 44. 45, traversant la paroi d'extrémité 15, 17 et débouchant vers l'extérieur, et une cloche concentrique 46, 47 le coiffant et ménageant autour de ce tuyau un espace annulaire d'écoulement pour fluide liquide de l'intérieur de ces boites 9 et 10 vers l'extérieur. Ces espaces annulaires et les tuyaux centraux 44, 45 forment respectivement des siphons d'évacuation. Les extrémités supérieures libres des tuyaux 44, 45 ont un niveau supérieur ou égal à celui des seuils 22, 23 des entrées 18, 19 des boîtes 9 et 10 de manière que le niveau maximale de liquide retenu par les dispositifs de siphonnage 42 et 43 soit égale au niveau de liquide retenu par ces seuils 22, 23 avant son déversement par trop plein.According to the invention in boxes 9 and 10, the water drainage holes formed by holes drilled in the end walls 15 and 17 are eliminated. Siphoning devices 42, 43 are formed respectively in each of these boxes 9 and 10 upstream of an obstacle arranged in the path of the water currents created respectively by the admitted water jets 32, 33. In the example illustrated, this obstacle is constituted by one of the deflectors 40, 41. This obstacle or deflector creates eddies and an overpressure in the admitted water current which cause the water level to rise at this location of the boxes 9 and 10 and cause the priming of these siphoning devices. These siphoning devices comprise a pipe 44. 45, passing through the end wall 15, 17 and opening towards the outside, and a concentric bell 46, 47 covering it and providing an annular space for fluid flow around this pipe. liquid from the inside of these boxes 9 and 10 to the outside. These annular spaces and the central pipes 44, 45 respectively form drain siphons. The free upper ends of the pipes 44, 45 have a level greater than or equal to that of the thresholds 22, 23 of the inlets 18, 19 of the boxes 9 and 10 so that the maximum level of liquid retained by the siphoning devices 42 and 43 is equal to the level of liquid retained by these thresholds 22, 23 before it overflows.

Les dispositifs de siphonnage 42, 43 sont ainsi disposés dans des endroits où sont formés des remous dans le courant d'eau d'entraînement des produits. La puissance des remous facilite leur amorçage même dans le cas où les produits utilisés sont pulvérulents ou pourvus d'une grande viscosité. Dans les boites 9 et 10, une combinaison d'un déflecteur 40, 41 et d'un dispositif de siphonnage 42, 43 permet de donner une grande efficacité à un fonctionnement de ces boîtes en boîtes universelles recevant indifferem- ment un produit pulvérulent ou liquide quel que soit son degré de viscosité.The siphoning devices 42, 43 are thus placed in places where eddies are formed in the product-carrying water stream. The power of the eddies facilitates their priming even in the case where the products used are powdery or provided with a high viscosity. In the boxes 9 and 10, a combination of a deflector 40, 41 and a siphoning device 42, 43 makes it possible to give great efficiency to the operation of these boxes in universal boxes receiving either a pulverulent or liquid product whatever its degree of viscosity.

Quand la boite 10 par exemple est remplie d'une dose de produit, au moment de la distribution de ce produit, un jet d'eau 32 injecté à travers l'entrée 19 forme un courant d'eau dans lequel le déflecteur 41 crée des remous violents qui contribuent à augmenter l'action tourbillonnaire d'entraînement de ce courant d'eau autrement dit à soulever et entraîner le produit, et l'évacuer par déversement par trop plein par dessus le seuil 23. Pendant ce temps à l'endroit du dispositif de siphonage 43 ces remous soulèvent l'eau admise à un niveau supérieur à celui du seuil 23 et de l'extrémité supérieure libre du tuyau 45 et provoquent l'amorçage de ce dispositif de siphonnage 43. Le produit s'évacue ainsi également à travers ce dispositif.When the box 10 for example is filled with a dose of product, at the time of dispensing of this product, a water jet 32 injected through the inlet 19 forms a stream of water in which the deflector 41 creates violent eddies which contribute to increase the swirling action of entrainment of this current of water in other words to lift and entrain the product, and evacuate it by overflow over the threshold 23. Meanwhile at the place of the siphoning device 43 these eddies raise the water admitted to a level higher than that of the threshold 23 and of the free upper end of the pipe 45 and cause the priming of this siphoning device 43. The product thus also evacuates through this device.

Quand le jet d'eau 32 est coupé, le siphonnage continue à travers le dispositif 43 pour vider la boite 10 et la rendre prête pour recevoir une nouvelle dose de produit. Le fonctionnement de la boîte 9 est analogue au fonctionnement ci-dessus de la boîte 10.When the water jet 32 is cut, the siphoning continues through the device 43 to empty the box 10 and make it ready to receive a new dose of product. The operation of the box 9 is analogous to the above operation of the box 10.
